Another thought, which seems to me to be expressed in this wonderful exclamation of our Lord's, is--that this faithlessness bound Christ to earth, and kept Him here. As there is not anger, but only pain, so there is also, I think, not exactly impatience, but a desire to depart, coupled with the feeling that He cannot leave them till they have grown stronger in faith. And that feeling is increased by the experience of their utter helplessness and shameful discomfiture during His brief absence They had shown that they were not fit to be trusted alone. He had been away for a day up in the mountain there, and though they did not build an altar to any golden calf, like their ancestors, when their leader was absent, still when He comes back He finds things all gone wrong because of the few hours of His absence. What would they do if He were to go away from them altogether? They would never be able to stand it at all. It is impossible that He should leave them thus--raw, immature. The plant has not yet grown sufficiently strong to take away the prop round which it climbed. 'How long must I be with you?' says the loving Teacher, who is prepared ungrudgingly to give His slow scholars as much time as they need to learn their lesson. He is not impatient, but He desires to finish the task; and yet He is ready to let the scholars' dulness determine the duration of His stay. Surely that is wondrous and heart-touching love, that Christ should let their slowness measure the time during which He should linger here, and refrain from the glory which He desired. We do not know all the reasons which determined the length of our Lord's life upon earth, but this was one of them,--that He could not go away until He had left these men strong enough to stand by themselves, and to lay the foundations of the Church. Therefore He yielded to the plea of their very faithlessness and backwardness, and with this wonderful word of condescension and appeal bade them say for how many more days He must abide in the plain, and turn His back on the glories that had gleamed for a moment on the mountain of transfiguration.
